com.microsoft.sqlserver.jdbc.SQLServerException: 通过端口 1456 连接到主机 localhost 的 TCP/IP 连接

刚装的SQL SERVER2008无法用MYECLIPSE总是无法连接，报错

com.microsoft.sqlserver.jdbc.SQLServerException: 通过端口 1456 连接到主机 localhost 的 TCP/IP 连接失败。错误:“Connection refused: connect。请验证连接属性，并检查 SQL Server 的实例正在主机上运行，且在此端口接受 TCP/IP 连接，还要确保防火墙没有阻止到此端口的 TCP 连接。”。

测试代码

连接数据库

package pinhong.dao;
import java.sql.*;
public class DataBaseDao {
public final static String DRIVER ="com.microsoft.sqlserver.jdbc.SQLServerDriver";
public final static String URL = "jdbc:sqlserver://localhost:1456;DataBaseName=pinhong;";
public final static String NAME = "sa";
public final static String PASSWORD = "suiwind5211314";
public Connection getCon() throws ClassNotFoundException, SQLException{
Class.forName(DRIVER);
Connection con = DriverManager.getConnection(URL, NAME, PASSWORD);

return con;
}

}

测试

package pinhong.dao;
import java.sql.*;
public class text {

/**
* @param args
*/
public static void main(String[] args) {
Connection con = null;
DataBaseDao dbo = new DataBaseDao();
ResultSet rs = null;
PreparedStatement pstmt = null;
try {
con = dbo.getCon();
pstmt = con.prepareStatement("select * from TBL_USER");
rs = pstmt.executeQuery();
while(rs.next()){
System.out.println(rs.getString(1));
}
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

已经用JDBC了可是就是连接不上，1433端口不好使之后我又用了别的端口
貌似是端口没有启动，求大侠帮助

Answer 1

去百度搜如何查看启用端口

Answer 2

你的端口应该不对 ，去数据库 新建查询中打 exec sys.sp_readerrorlog 0, 1, 'listening' 查一下你的端口是多少
